Measurement of the Top Quark-Antitop Quark Differential Cross Section, dsigma/dM(tt), in Proton-Antiproton Collisions at Center of Mass Energy = 1.96 TEV
type: CreativeWork
description: I present a measurement of the tt¯ differential cross section, dsigma/dMtt¯, in pp¯ collisions at s = 1.96 TeV using 2.7 fb-1 of CDF II data. I find that dsigma/dMtt¯ is consistent with the Standard Model expectation, as modeled by PYTHIA with CTEQ5L parton distribution functions. I set limits on the ratio kappa/M Pl in the Randall-Sundrum model by looking for Kaluza Klein gravitons which decay to top quarks. I find kappa/MPl > 0.16 at the 95% confidence level.
